.SPECIFICATION forming part of Letters Patent N o. 674,453, dated May21, 1901. Application iled December 3, 1900. Serial No. 38,534. (Nomodel.)

To @Zt whom, it' wila/y concern.

Be it known that we, JOHN R. CARTER, of Augusta, in the county ofBracken and State of Kentucky, and JOSEPH E; HAUSFELD, of Cincinnati, inthe county of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Stove-Doors; and we do hereby declare thefollowing to be afull, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to an improvement in stove-doors, and moreparticularly to doors hinged at their lower edge, the object of theinvention being to provide a door of this character with improved meansfor returning it' to its closed position when opened and with improvedmeans for holding it in its lower open position.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View illustrating ourimprovements. Fig. 2 is a view, partly broken away, illustrating thespring for closing the door. Fig. 3 is a view in section of the same,and Fig. e is a View of the door removed.

1 represents a stove-front having an opening therein and formingineffect a door-frame, and2 our improved door provided at its lowercorners with oppositely-disposed trunnions 3r and 4, respectively. Thetrunnion Liis mounted in a semicircular bearing 5 in a housing 6,secured to the stove-front by screws or bolts, as shown, and made withan outwardly-projecting lug 7, forming a shoulder or stop, against whichthe door 2 strikes when in its lowest open position and forms a rest orsupport therefor. The other trunnion 3 is provided with a cylindricalbifurcated enlargement 8 and is supported in a housing 9, removablysecured to the stove-front by means of screws or bolts, as shown, andprovided with an outwardly-projecting lug 10, similar to lug 7, toassist the latter in supporting the door in its open position.

The stove-front 1 and housing 9 are made with opposite semicylindricalrecesses 11 to receive a coiled spring l2, one end of which is bent toextend across one end of the springcoil and disposed in the bifurcatedenlargement 8, and the other end 13 of the spring extends downwardly atright angles to the coil and is held in an elongated recess 14. in thestove-front 1 by the housing 9. It will thus be seen that the parts canhe readily assembled, as the spring 12 can be inserted in the housing 9and the latter secured to the front of the stove and when so securedwill hold the trunnion and spring firmly in'their proper positions. Y

The lower edge of the door, adjacent to the trunnions 3 and 4., isprovided with cam-faces 15, and the housings 6 and 9 are made withopenings to permit the free passage of the cams; but the latter willwhen the door is almost to itsfull open or lowest position closelyengage the front of the stove and owing to the close binding of the camsagainst the stove-front will hold the door in its open position.

A latch 16, of rany desired construction, is provided on the door toengage a keeper on the stove-front and hold the door in its closedposition.

The operation of our improvements is as follows: When the door 2 isopened, the enlargement 8 is turned and contracts spring 12, whichlatter,'if the door is released before it reaches its extreme openposition, will close the same; but if the door is forced down to itsfnllopen position the cams 15 will wedge against the stove-front andhold the door open until raised slightly to release its cams, when thespring will complete the closing of the door. It will thus be seen thatwhile the cams serve to hold the door open they likewise serve toprevent jarring and rattling thereof when thrown with force to its openposition, for the cams will begin to engage the stove-front before thefull-open position is reached, and thus relieve the shock incident to asudden stop thereof by the lugs 7 and 10, and the binding of the camswill prevent any rebound.

Various slight changes might he resorted to in the general form andarrangement of the roo several parts described Without departing fromthe spirit and scope of our invention. Hence We would have it understoodthat We do not Wish to confine ourselves to the exact constructionherein shown and described; but,

Having fully described our invention, what We claim as new, and desireto secure by Let- 1 ters Patent, is-

l. The combination with a door-frame and a door, of trunnions on thedoor, bearings on the frame for the trunnions, a cam on the door toengage the .frame when the door is opened and a spring for closing thedoor when the cam is released.

2. The combination With a doorframe and a door, of trnnnions on thedoor, bearings on the frame for the trnnnions, a bifureated enlargementon one trunnion, a coiled spring loose on said enlargement, one end ofthe spring extending across the coil thereof and disposed in `thebifurcated enlargement, means on the frame for securing the other end ofthe spring against movement, and a device on the door cooperating withthe frame to retain the door fully open. 3. The combination with astove-front having an opening therein, and a door for closing saidopening, of oppositely-di-sposed trunnions on the lower corners of thedoor, housings removably secured to the stove-front to form bearings forthe trunnions, an enlargement on one trunnion, a coiled springsecuredagainst rotation on said enlargement, the housing and stove-frontrecessed to receive the enlarged end of the trunnion and spring thereon,cams on said door to engage the stove-front and act in opposition to thespring to retain the door open, and lugs or shoulders on both of saidhousings to limit the opening of the door.

4. The combination with a stove-front having an opening therein, and adoor for closing said opening, of oppositely-disposed trunnions on thelower corners of the door, housings removably secured to the stove-frontto form bearings for the -trnnnions, an enlarge ment on one trnnnion, aspring connected at one end to the enlargement, the housing having arecess .to receive the spring-and enlargement, cams on said door toengage the-stovefrontandact in opposition lto the spring to retain thedoor open, and lugs or shoulders on both housings to limit the openingof the door.

In testimony whereof we have signed this specification in the presenceof two subscribing Witnesses.
